Outline of Final Research Achievements

For the purpose of advanced GPR techniques for detecting underground unexploded ordnances (UXOs) and landmines, wider frequency range antennas were developed by their shape deformations. After estimating several shapes of bow-tie antennas the pentagonal bow-tie antenna was 81 MHz wider operating frequency range and 24 % higher high/low operating frequency ratio than the regular triangle one. This antenna was more useful than the conventional regular triangle bow-tie antenna and the Vivaldi antenna and was expected to perform the higher detecting capability and the higher imaging quality.
